To all whom it may concern:

Be it known that I, ALFRED L. BERNARDIN,

a citizen of the United States, and a resident of Evansville, in the county of Vandorburgand State of Indiana, have invented a certain new and useful Improvement in Bottle-Caps, of which the following is a specification.

My present invention relates generally to bottle caps, and more particularly to catsup screw-caps of the pieced type, prior to the production of which catsup screw caps of the length required were of the seamless or drawn type, the manufacture of which represents such a strain on the metal as to make it impossible to apply lacquer or other coatings in the sheet, since such coatings would be destroyed by the drawing operation Since pieced cap constructions represent only bending, various inexpensive coatings can be efiectively applied in the sheet without appreciable damage during the making of the cap.

Pieced cap constructions up to the present time have, however, presented side seams extending the full length of the cap, so that thelower or inner threaded section thereof must have a beaded inner or bottom edge in order to keep the bodies in round or truly cylindrical shape. only a dirt catcher, but detracts from the appearance of the cap in general, and the pieced cap construction as now utilized is objectionable for these reasons.

In my present invention I aim to produce a pieced cap, the inner or lower section of which, having the threads, may be drawn by virtue of being relatively shallow and, being seamless as finished, the usual beaded edge may be dispensed with.

In the accompanying drawing wherein my invention is illustrated:

Figure 1 is a perspective view of the neck portion of a bottle provided with my improved cap;

Fig. 2 is a vertical section through the cap as shown in Fig. 1;

Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2;

Fig. 4 is a side view partly broken away and in section, illustrating a slightly modified form, and

Figs. 5, 6, and 7 are partial vertical sections illustrating modified forms of joints between the two pieces or sections of the cap.

This beaded edge is not As seen in the several figures, the lower or inner section 10 of the cap proposed bymy invention, is of seamless construction, and threaded for engagement with the threads of a bottle neck 11, this section or piece of the cap terminating in an inner or lower raw edge 12 by virtue of its seamless construction, which obviates necessity of having a surrounding bead required at the lower inner edge of the pieced cap constructions now in use, by reason of their vertical seams.

The lower inner section 10 may be joined at its opposite edge to the lower inner edge of the upper outer piece or section 13 of the cap, by means of an externally interfolding seam 14, as seen in Figs. 1, 2, and 3, or by any one of a number of other type seams, for instance, an internally interfolding seam 15, as in Fig.6, an outer lapped folding seam 16, as seen in Fig. 6, or a crimped seam 17, as shown in Fig.

It is to be understood that, in forming the inner piece or section 10 of the cap, a shell is drawn up andi its top blanked out, damage to the lacquer or other coating to be applied in the sheet being prevented by virtue of the comparative shallowness of such shell with respect to the full length of the cap.

In Figs. 1 and 2 I have shown the upper or outer section l3'of the cap formed of a bent strip and have utilized the blanked out top of the lower seamless shell 10 as a top 18 for the upper section as shown. The upper section may, however, be drawn up in a single piece, as seen at 19 inFig. 4.

It is obvious from the foregoing that the construction provided by my invention obviates the disadvantages firstabove referred to in two-piece-cap constructions,- and sti l renders it optional as to the particular hori-' zontal seam between the two pieces of the cap aslwell as the particular construction of the upper outer piece or section thereof.

Although my invention aims to do away with the too rounded lower edge'of the lower section 10, as above described, it is obvious that if desired for purposes of ornamentadepth in seems-ct to that sit lete can, ensures its lornie-tion in a sle drawing operation. which the lacquer usual coating Will stand Without material alarm.

l urthermore, in connection with a seamless lower section es l0, deeper threads lower section of which has a Vertical seam for the purpose of pullingsuch seam through the thread dies, and which gripping means in the ordinary formation frequently impair and go so far as to totally destroy the lacquer or coated finish of the upper part.

1 claim: v

1. A bottle cap having a, pair of sepa rately formed and longitudinally alined shells, and a horizontal seam permanently connecting the adjacent edges of said shells, one shell of which is drawn from a single piece having its top removed, and'the outer shell of which has a vertical-seam and atop joined by a seam thereto.

2-. A bottle cap having; retely formed and longitudinally alined cylindrical. shells, and a horizontal-seam connecting the adjacent of said shells, the one shell of Whieh is drawn froin a single piece With its top removed, and has a raw free edge 3. A bottle cap having a pair of separately formed and longitudinally alined cylindrical shells, and a horizontal seam 1 connecting the adjacent edges of said shells,

one only of. which shells is drawn froma single iece of material and threaded. I
